SIDEN is a distributed network discovery tool used for intrusion detection research. The current SIDEN architecture allows you to simulate coordinated/distributed network probes by a group of attackers.

SIDEN has been tested successfully on the OpenBSD and FreeBSD operating systems. If you try SIDEN and it works on any other platform, please contact me. Yes, it sounds interesting that I haven't even tested it out on the popular Linux platform. There should be little reason why it won't work on other platforms (especially UNIX variants), since it's fully implemented in Perl.
